Problem with rectilinear infill
Hi
I had some problem with rectilinear infill especially over larger areas.
The infill starts to break up after a couple of passes, if itś a smaller area I have managed to fix it by pausing the print and then carefully sandpaper it and doing so a couple of layers it usually stabilizes.
Is there any settings I can do so I won´t have this problem?
Every answer appreciates
Yours

RE: Problem with rectilinear infill
Infill should not be breaking up like that. Try setting your infill speeds lower to give the filament time to bond. Or alternatively print it hotter by 5-10 degrees. Have you done a temperature tower for that filament to find its best printing temp with your printer ? Or any other filament calibration at all ?

Can you post a picture with the first layer?

I have not done that tower you are talking about and the only settings I have done is the temperature for the different filament I have
There are lots of settings that you can change and for a newbie itś hard to understand what effect they have on the print
I will try the speed and/or temperature change
Thanks

What fillament?

I dońt have a picture but the course of the print is that itś start with the outline of the print and then there are a couple of layers with solid infill (as you can see on the pic) and after that the rectilinear infill starts.
Dońt know if thatś what you are asking for.

Try slowing down your infill speeds. You didn't mention what settings you're using, but Prusa's infills speeds tend to be optimistically high. While you can print very quickly with PETG, infill is tricky. A quick test would be to dial speed back to 50% using the front knob mid-print. If that helps, you know your answer. Adjust your slicer settings accordingly. Alternatively, you can adjust the Maximum volumetric speed in your filament profile so you don't have to play with other settings. I'd start at 5mm^3/s, then gradually work up to see how fast it will go and still print well.

add:north has a very nice printing guide for their filaments here.
